First of all, what we need is that it has a good compressive capacity and can ensure its good operation under a variety of variable water pressure, which is also an important factor we must consider in order to better play the performance advantages of such facilities. Frequently check whether the gate plate and gate slot are jammed, and timely place the jammed object to ensure the position is in the middle, so that the equipment can operate normally. Mainly water conservancy equipment to control water flow. 3. Cast iron gate adopts embedded steel plate or embedded bolt device, which is convenient for installation, commissioning, operation, protection and long service life. If necessary, it can also use high-pressure cast iron, aluminum silver alloy and other insoluble metals. As cast iron gate. In the process of using the machine, it is necessary to inject lubricating oil from the oil filling hole at any time, and keep enough lubricating oil regularly, so that the maintenance of the machine can extend the service life of the hoist, and regularly carry out and apply new oil to the oil scale of the screw, so as to prevent the machine from corrosion and damage. If these conditions are met, we can carry out the next assembly and placement work, so as to make the later work more smoothly and improve the efficiency of the actual operation. Before spraying, the gate surface shall be sand blasted to remove the old live layer, rust, and the white luster of the metal, so as to ensure the rough surface and facilitate the coating adhesion. Of particular note. It is necessary to check whether the nuts and screws in various places are normal. If they are loose, they should be tightened, so that they will not show any condition in the process of application. (III) coating selection: cooperate with cathodic protection. The following coating cast iron gates can be selected on the front gate surface of the device, which are widely used in water conservancy and hydropower, municipal construction, water supply and drainage, aquaculture, agricultural water conservancy construction and other projects.首先我们需要的就是它具备良好的抗压能力，能够在各种无常变化的水压之下还能够保证其良好的工作运行情况，这也是我们为了更好的发挥这类设施的性能优势所必须要考虑的一个重要因素。经常检查闸门板与闸槽是否卡涩，及时将卡涩物，保证位置置中，使设备正常运行。主要是控制水流量的水利设备。3，铸铁闸门选用预埋钢板或预埋螺栓式装置，装置，调试，运用，保护便利，运用寿命长。必要时也可用高压铸铁，铝银合金等不溶金属。作为铸铁闸门。机器在使用的过程中，需随时从注油孔注入润滑油，而且要经常保持足够的润滑油，这样对机器的保养可以延长启闭机的使用寿命，还要定期对螺杆的油垢进行并涂护新油，以防止机器锈蚀而损坏。如果这些条件都具备了的话，我们才能够进行下一步的组装安置工作，这样才能使后期的工作进行地更加的顺利，从而提高实际作业的效率。喷镀前，闸门表面采用喷砂处理，除净旧活层，锈蚀物，泊垢氓霸山金属白色光泽，保证表面毛糙，以利喷镀层附着。尤其值得注意的是。
必需要查看各个地方的螺帽，螺丝都是不是正常的，若是用松动的话就要把它拧紧，这样在运用的过程中就不会呈现什么状况了。(三)涂料选舞：配合阴极保护。铸铁闸口在装置前闸门表面可选用以下涂料铸铁闸门广泛应用于水利水电，市政建设，给水排水，水产养殖，农用水利建设等工程。
